A nut includes a body having a neck connected to one end thereof and the neck has a breaking portion formed on the first end thereof. The breaking portion is connected to the end of the body. The thickness of the breaking portion is smaller than that of the neck. A polygonal holding portion is formed to the second end of the neck. The body has a threaded hole defined axially therethrough and the holding portion has a through hole which communicating with the threaded hole. Once the body of the nut is locked to a bolt, the breaking portion is broken and only the body is mounted onto the bolt. The body has a smooth cylindrical outer face.

    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring to FIGS. 2 and 3, the nut 2 of the present invention comprises a tubular body 20 having a neck 22 connected to one end thereof. The neck 22 has a breaking portion 23 formed on the first end thereof, and a polygonal holding portion 24 is formed to the second end of the neck 22. The polygonal holding portion 24 is a hexagonal holding portion. The breaking portion 23 is connected to the end of the body 20. The thickness of the breaking portion 23 is smaller than that of the neck 22. The body 20 has a threaded hole 25 defined axially therethrough. The holding portion 24 has a through hole 26 which communicating with the threaded hole 25.
  • When in use, as shown in FIGS. 4 and 5, a bolt 3 extends through an object 4 and the threaded section of the bolt 3 extends beyond the object 4. The nut 2 is mounted to the threaded section of the bolt 3 and the nut 2 is rotated by using a tool holding the holding portion 24. The threaded section of the bolt 3 is threadedly connected to the threaded hole 25 of the body 20 of the nut 2 when rotating the nut 2. When the nut 2 securely contacts against the object 4, the tool is continuously rotated, the torque applied to the holding portion 24 breaks the breaking portion 23 because the thickness of the breaking portion 23 is thinner than the rest portion of the neck 22 as shown in FIG. 5. The holding portion 24 and the neck 22 are then removed from the body 20 and the threaded section of the bolt 3. Because the body 20 has a smooth cylindrical outer face 21 so that no tool can clamp the body 20 to remove the body 20 from the bolt 3.
  • FIGS. 6 and 7 show the second embodiment of the present invention, wherein the difference between the first embodiment and the second embodiment of the present invention is that the body 20 has a smooth tapered outer face 27.
  • Similarly, when in use, as shown in FIGS. 8 and 9, a bolt 3 extends through an object 4 and the threaded section of the bolt 3 extends beyond the object 4. The nut 2 is mounted to the threaded section of the bolt 3 and the nut 2 is rotated by using a tool holding the holding portion 24. The threaded section of the bolt 3 is threadedly connected to the threaded hole 25 of the body 20 of the nut 2 when rotating the nut 2. When the nut 2 securely contacts against the object 4, the tool is continuously rotated, the torque applied to the holding portion 24 breaks the breaking portion 23 because the thickness of the breaking portion 23 is thinner than the rest portion of the neck 22 as shown in Fig. 7. The holding portion 24 and the neck 22 are then removed from the body 20 and the threaded section of the bolt 3. Because the body 20 has a smooth tapered outer face 27 so that no tool can clamp the body 20 to remove the body 20 from the bolt 3.
  • While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
